March 8, 1751 - Ferdinand I of the Two Sicilies

Ferdinand I (Italian: Ferdinando I; 12 January 1751 – 4 January 1825) was King of the Two Sicilies from 1816 until his death. Before that he had been, since 1759, King of Naples as Ferdinand IV and King of Sicily as Ferdinand III.

Ferdinand was born in Naples as the third son of King Charles VII and Queen Maria Amalia. In August 1759, Charles succeeded his half-brother Ferdinand VI of Spain as King Charles III, but treaty provisions made him ineligible to hold all three crowns. On 6 October, he abdicated his Neapolitan and Sicilian titles in favour of his third son, Ferdinand, because his eldest son Philip had been excluded from succession due to intellectual disability and his second son Charles was heir-apparent to the Spanish throne. Ferdinand was the founder of the cadet House of Bourbon-Two Sicilies.
